You are quite right. Not all KYCs are actually safe for one to do. Apart from ICOs, some airdrops sometimes require KYC of which you will later realize the airdrop to be fake. What then happens to the information they collected? Will it still be safe?
I agree with you, I do not believe in airdrops that use KYC, if it turns out to be a scam then the thing I am worried about is the data that has been given, we are afraid that if the data provided is misused, I think it is not safe to provide data for KYC on airdrop
